You should check the mask or nasal pillows after each cleaning. The silicone mask cushion and the silicone nasal pillows were designed to last up to 12 months with proper care. Although silicone is not susceptible to hardening, it can tear. The actual life of the nasal mask or pillows can vary greatly, depending upon use, the industry average for a complete unit with proper care and maintenance seems to be about 18 to 24 months. Replace the mask when it leaks air excessively, there is a tear in the cushion, or it becomes uncomfortable to wear.

Step 1.
Remove the headgear from your mask or nasal pillow shell. Disconnect the mask or shell, swivel or Whisper Swivel from the tubing.

NOTE: There is no need to remove the support ring, spacer, or rotating connector from certain masks before cleaning them, but you may want to do so to clean the parts more thoroughly.

Step 2.
With a soft cloth (or a disinfectant cloth), gently wash (or wipe) all the parts of the mask, the shell and pillows, the swivels in a solution of warm water and mild un-scented shampoo or un-scented dish detergent.

DO NOT use any cleaners containing fragrance, conditioners or moisturisers as these will leave a residue. Be sure to thoroughly clean the mask cushion flaps or the nasal pillow.

Step 3.
Rinse thoroughly. If any part or parts still seem to be oily, wash them again.

Step 4.
If desired, you can disinfect the tubing, mask parts, the shell and pillows, the swivels in a cold sterilising solution, consult your local chemist, following the manufacturer's directions closely. You may choose to use a white vinegar and distilled water solution, mixing 1 part white vinegar and three parts distilled water. Allow all items to soak for 20 minutes. Make sure you thoroughly rinse the items after disinfecting them. Any residue left on the parts may shorten their useful life and/or irritate your skin.

Step 5.
Let every thing dry completely before using them again. To make sure all parts of the system are completely dry, put the system together and run the unit for about 30 minutes before using.

These items should be cleaned a minimum of once each month.

Step 1.
To maximise the life of the headgear and chinstraps, hand washing with a standard laundry detergent is recommended.

NOTE: NEVER USE BLEACH. Before washing, remove the headgear and chinstraps from all other parts of the machine and mask. Fasten all hook tabs to the pile straps to protect other garments in the laundry.

Step 2.
Air dry or machine dry WITHOUT HEAT. Machine drying with heat may cause wrinkles or render the elasticity useless. NEVER IRON the headgear or chinstraps.

BREEZE & DREAMSEAL USERS: NEVER wash or immerse the rear piece of the unit in any cleaning solution, use a damp cloth rinsed in the solution and well wrung out.

Always use distilled water in your humidifier.
Detatch humidifier from your machine and mask prior to cleaning.

The humidification chamber should be cleaned daily or after each use. After the heater plate has cooled, disconnect the tubes from the top of the humidification chamber and remove it from the heater base.

Discard any water remaining in the humidification chamber if you are not using distilled water.

Wash the chamber top, base, deflectors, and supply tubing in mild dish washing detergent. Rinse thoroughly at least twice and air dry. Make sure there are no residual signs in the chamber of the detergent.

Disinfect chamber top, base, deflector, and tubing weekly in a mild solution, see chemist. Follow label directions. Rinse thoroughly at least twice after disinfecting.

Inspect the chamber, base, deflector, and tubing to ensure no residue remains after cleaning and sterilising.
